A fluorescent oxaliplatin derivative for investigation of oxaliplatin resistance using imaging techniques.


PMID 29043454

Abstract

Oxaliplatin is the backbone of chemotherapy for advanced colorectal cancer and undergoes clinical trials for treatment of other tumour entities. However, acquired resistance is a major hurdle. Confocal microscopy is a useful tool to get an insight into the mechanisms of resistance but it requires fluorescent compounds. This work describes the synthesis of the novel oxaliplatin derivative (CFDA-oxPt) featuring 5(6)-carboxyfluorescein diacetate and evaluation of its applicability for the investigation of oxaliplatin resistance using imaging techniques. CFDA-oxPt was somewhat less cytotoxic than oxaliplatin in sensitive colorectal cancer cells, with EC
